Which Resin Is Recommended for 3D Print Finishing?

Choosing the right resin for 3D print finishing can make all the difference when aiming for a smooth, professional look. Selecting the right type will help you enhance durability and visual appeal with less post-processing.

Why Use Resin for 3D Print Coating?

Applying a resin coating to your 3D prints helps eliminate unsightly layer lines and improves overall surface quality. Besides a glossy, seamless finish, coatings such as 3D Finish Fast Coating Epoxy Resin also boost mechanical strength, providing extra protection for both decorative and functional prints.

Choosing the Right Resin for Your Needs

Epoxy resins: These are popular for 3D prints as they offer strong adhesion to materials like PLA, ABS, and LAYWOOD. Look for fast-curing types (set in around 4 hours at room temperature) for efficient workflow and a smooth, polishable surface.
UV resins: One-component UV resins are an option for quick, thin coats and instant curing under UV light, but tend to be less suitable for thicker coatings.
Mixing ease: Resins like “One-2-One” with a simple 1:1 mixing ratio can make preparation easier for crafters and hobbyists, while more specialised epoxy systems are tailored for bonding and detail preservation on 3D prints.

How to Apply Resin Effectively

Before coating, ensure your print is clean, dry, and lightly sanded for best adhesion. Mix the resin components according to the manufacturer’s instructions—precision here avoids tacky spots. Use a brush or spatula to apply a thin, even layer, allowing any bubbles to rise and pop. For epoxy coatings like 3D Finish, curing typically completes in 4 hours at 20°C, after which the piece can be sanded or painted if desired. For UV resins, cure thoroughly with a UV lamp and avoid exceeding the recommended layer thickness.
